I'm just recently after making the move from Xp to Lubuntu on a Dell Inspiron 1501. After hours of meddling I managed to get the issue with the wireless sorted. (Although I tried so many steps I'm still unsure which one did the trick! ). I find it great, laptop has become practically silent while running and is working great for the basics.

My question is as follows and I'd be grateful for the help, I have tried to use a Lubuntu Live USB on another Dell laptop with the same broadcom issue, is it possible to copy a certain set of folders from the laptop that is working and move them across?

I saw it mentioned on another site while searching the initial problem but cannot remember where!

For wireless in ubuntu, if you find the driver isnt working out of the box,

just plug in a ethernet cable, or tether your phones internet connection via usb, and go to the "additional drivers" (system settings > software sources > additional drivers)menu, this will download the wireless driver you need. No hours of meddling
